@Anil-Kulkarni If you don't have a soldering iron and you're asking these kinds of questions, I am going to hazard a guess you're not terribly experienced, and in that case I am offering you some advice: don't choose the cheapest possible iron and don't use lead-free solder. Lead-free has its advantages, yes, but leaded solder is a lot easier to work with, especially if you ain't experienced at soldering.
